[FEATURE REQUEST] RTL: set RTL per screen or new modes per screen

I don't want to add another parameter to the default service cal because there are already plenty of parameters. But new modes/service calls for RTL seem possible.

It can be a boolean parameter like default font in the service. Adding that would be awesome.

If you find the solution helpful, consider adding it to the wiki section.

Idodov, very nice idea of the LedMatrixAlbumArt, thanks for sharing:)

Also thank you Lubeda and Andrew of course, I know you've been looking for a solution for this FR and similar cases.

I myself, using a lot of both Heb+Eng strings for different scenarios,
and an option to allow setting RTL per screen would be super helpful and appreciated! 🙏

As far as I know too, unfortunately, we can't use optionals in the ESPHome service-calls, so I understand the hesitation,
but may I suggest a middle-ground solution?
Can we have an option, to set the rtl flag per default_font and special_font (or even just for special_font)?
Something like:

ehmtxv2:
  id: rgb8x32
  default_font_id: ehmtx_font
  special_font_id: ehmtx_font_heb
  special_font_rtl: true  # default will be `false`

That way, anytime we select the special_font using the current service-calls, it will render with RTL.

I think this solution will be most suitable considering the current limitations, and doesn't break any current usages.

What do you think?
